1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Gastric neuroendocrine tumors (NETs), derived from enterochromaffin-like cells, commonly exhibit submucosal extension and manifest as submucosal tumor (SMT)-like lesions during endoscopy. We report a rare case of a gastric NET with endoscopical unusual pedunculated and reddish morphology. A 15-mm lesion in the gastric body showed histologically proved to be a grade G2 NET. Endoscopic submucosal dissection was performed, followed by surgery due to lymphatic invasion. Histological examination of the background gastric mucosa in the resected specimen revealed features of autoimmune gastritis, consistent with a type 1 gastric NET according to the Rindi classification. Recognition of such atypical morphology may aid diagnosis.
